-One of the 'features' of overlayfs is that depending on whether a file
-is on the upper or lower dir you get back a different device from stat.
-That breaks our lxc_rmdir_onedev.
-
-So at lxc_rmdir_ondev check the device of the directory being deleted.
-If it is overlayfs, then skip the device check.
-
-Note this is unrelated to overlayfs snapshots - in those cases when you
-delete a container, /var/lib/lxc/$container/ does not actually have an
-overlayfs under it.  Rather, to reproduce this you would
-
-sudo mkdir /opt/{lower,upper,workdir}
-sudo mount -t overlayfs -o lower=/opt/lower,upper=/opt/upper,workdir=/opt/workdir \
-	lxc /var/lib/lxc
-sudo lxc-create -t download -n c1 -- -d ubuntu -r trusty -a amd64
-sudo lxc-destroy -n c1
